Top Risks

• NewTab override combined with uninstall/install URL hijacking — classic monetization shell pattern.
• Privacy policy URL returns HTTP error; policy effectively inaccessible, scoring as unfetched.
• Operator cluster of 23 extensions under same dev email signals mass-production wallpaper/newtab farm.
• mlionltd.github.io in js_external_hosts is an uncontrolled third-party GitHub Pages domain.
• innerHTML DOM-XSS sink with no CSP present elevates injection risk on new-tab page.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to index.html; replaces every new-tab page for all users.
• uninstall_url_hijack crx setUninstallURL targets gameograf.com with UTM params — confirmed uninstall hijack.
• install_url_hijack crx onInstalled opens gameograf.com with UTM install campaign params.
• operator_cluster api 23 extensions share same dev email; compound fingerprint matches 4 siblings — mass-production farm.
• privacy_policy_fetch_error api privacy_policy_classification.fetched=false due to HTTPError; treated as no accessible policy.
• external_host_mlionltd crx mlionltd.github.io listed as JS external host — uncontrolled 3rd-party GitHub Pages domain.
• dom_xss_no_csp crx innerHTML sink in popup.js with csp_present=false elevates DOM-XSS risk on new-tab surface.
• no_developer_name store developer_name is empty string; reduces accountability signal despite verified_publisher=true.

Permissions Breakdown

• search medium Allows search provider manipulation; paired with newtab override this is a monetization surface.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary monetization vector for this extension type.
